invented certain new and useful. improvements in the telly band and rim which coact to secure the desired result.

In the drawings 1 show the tire A and the wheel hub and spokes as B with the telly as G and the telly band as D. in the peripheric lace oi the telly band I cut e:-:- ternal threads 1 circumferentially positioned and at such an angle that a partial rotation oi about four inches will grip the rim on the telly band. I then cut out s .ctions of said threads transversely across the said face, preferably tour oit' such sections are cut out, each of which is spaced from the other so there will be tour sections or: threadsand four blanks or unthreaded sections in the circumference of the hand. On one edge of said telly band an inwardly turned flange 7 is integrally formed thereon in which flange portion 1 cutan are shaped slot 2 with teeth 3-3 formed on one side oi the slot. U11 the other edge oil. said tie'lly band an outwardly extended l'lange ll is interrally forn'led. ll slot is cut through the telly U and also through said telly band i) tor the air valve stem, which slot is shown as l. The rim i use re ated tl'ireads running? eircumterentially around each. The said band 5 also has interruptcdj or spared apart sections of internal threads circun'ilierentially positioned and adapted to mesh with the threads 1, on the perinherv of said ielly band I). i

The sections oft intermeshing threads oil: the two rim bands 5 and 6 are out radially outward oi the unthreaded sections of the telly banch so that on the band 5. the ere ternal threads will occur"radially opposite the internal unthreaded sections and the internal threads will be radially opposite the external. unthreaded sections of the said band. ll. rack flange 12 is integrally formed on a portion of one edge of a tire gripping flange 13 which is integral with one edge oilt' said hand 5, while the enactingband (i has both an inwardly, and an outwardly turned Flange on one edge thereof. The in wardly turned flange let bears against the flange 7 oi the telly band, and the out-' is made of two coactlllfl bands 5 and 6 with intermeshing interwardly turned flange 15 will bear against and. grip the edge of the tire casing of the tire in opposition to the flange 13. A slotted are shaped opening 16 is provided in said rack flange 12 on said band 6 with one side oi said slot provided with teeth 9 to coact lllltl said bands f are moved.

with the teeth 3 of the slot 2. In the flange 14 an are shaped slot 17 is cut in alineinent With said slot 2 and on one side of said slot 17 teeth 10 are cut to coact with the teeth 3 of the slot 2. I provide a detachable closure plate 20 for said are shaped slot 17 which is shown in Figs. 9 and 10 to prevent dust and moisture from entering between the bands 5 and (5, and also between the said band 5 and the telly band C. The said closure plate may be easily removed to allow the insertion of the pinion carrying tool shown 'in Fig. (3, by which the On said closure plate 20 are provided teeth 22 adapted to engage the teeth 3 andlO of the respective slots 2 and 17 to lock the rim on the wheel. The operation of my invention is as follows :---The said band (3 is turned with the flanges 14: and 15 downward and the uninflated tire A is slipped on the band (3, the

i band 5 is then to be inserted within band 6 by the unthreaded sections of one band passing transversely the threaded sections of the other band. The flanges l5 and 13 will then be in gripping contact with the edges of said tire A and the intermeshing threads of said bands 5 and 6 will be-in partial alinement but not yet engaged. The pinion carrying tool is then inserted through the are shaped slots 16 and 17 with the teeth of the pinion engaging the teeth cut inboth of said slots as shownin Fig. 8, and by turning Sitltl pinion carrying tool as a hand brace both of said bands 5 and 6 are made to travel circumferentially but in opposite directions and the threadso't' the said bands 5 and 6 are made to engage and the band 5 is thus drawn laterally 'larther within the band 6. When the tire is then inflated the rim and tire thereon are secured on the wheel by inserting the air valve stem through the slot 4 and the rim is slipped over the felly band D by the unthreaded sections of the band 5 passing transversely the threaded sections of the telly band. The flange 14 of the band 5 will be adjacent yet not bear against the'flange 7 of the telly band, while the flange 8 cl? the fell band D will be adjacent but not bear against the flange 13 of the band 5. The pinion carry ing tool is then inserted through the are shaped slot 17 of the flange let and slot 2 of the flange 7 and into engagement with the teeth 3 of the slot 2 and the opposing teeth 10 in the slot 17, then by again turning the. pinion carrying tool as a hand brace, the rim and wheel are made to rotate on their axes and the sections o't circum[erential threads are made to engage and the llanges l1 and T, and 8 and l3 will be respeti\el v brought into gripping contact. Then by insorting the locking member 20 the rim is firmly and rigidly held in place on the wheel. The said locking member 21') is held in place by counter sunk tap bolts through the holes 21, the said locking member also acting as a closure.

Having thus described my invention aml its operation I desire to secure by Letters Patent and claim An automobile tire rim comprising a metal band having an inwardly and out-- wardly extended flange on one edge: inter rupted circumferentially disposed threads thereon; an are shaped slot cut in the inwardly extended flange with teeth cut in one side of said slot; a coacting metal band of less diameter than the first mentioned metal band and having an outwardly extended flange thereon with a portion formed into a rack flange; an are shaped slot in said rack flange with teeth out in one side of said slot; interrupted eircumterentialh disposed threads in said coacting metal band intermeshing with the circuml'erew tially disposed threads of the first mentioned metal. band; and means to engage the teeth in said slots to move said metal bands one within the other to engage the circumferentially disposed thrmds of one band with the like threads of the other band.

In testimony whereof I have atlixed my signature.
